Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is further elaborated.
see shown in Fig. 1 to Fig. 6, a kind of child's tricycle, this three-wheel vehicle 10 at least comprises underframe 101, is located at two wheel assemblies 20 of both sides, underframe 101 rear portion respectively, and each wheel assembly 20 includes the cardan wheel 1 be arranged on underframe 101.When this cardan wheel 1 rotates around rotation centerline OO ' vertically extend, namely the axial line of the S. A. of this cardan wheel 1 is arranged perpendicular to ground.Three-wheel vehicle is also provided with the lockout mechanism for being locked by cardan wheel 1, when this lockout mechanism is in released state, cardan wheel 1 is in free state and can universal rotational; When lockout mechanism is in the lock state, cardan wheel 1 is locked and can only straight-line travelling.
particularly, shown in each accompanying drawing, this cardan wheel 1 comprises the link span 11 be fixedly connected on underframe 101, relatively link span 11 can wheel seat 12, the wheel body 13 be arranged on wheel seat 12 of universal rotational, during lockout mechanism locking, namely be make relative locking between wheel seat 12 with link span 11 and non-rotatable, thus make wheel body 13 roll around Pivot Point Center line and linearly travel.
shown in each accompanying drawing, in the present embodiment, each wheel assembly 20 also comprises the attaching parts 3 be located at regularly on underframe 101 rear portion, and cardan wheel 1 is fixedly mounted on attaching parts 3 by link span 11.This cardan wheel 1 can adopt gauge member.Attaching parts 3 is the tie bolt 3 be located at regularly on underframe 101, and the link span of cardan wheel 1 11 is in the column vertically extended, and namely wheel seat 12 carries out universal rotational around the axial line of this link span 11.The bottom of tie bolt 3 offers the mounting hole 31 that can penetrate vertically for the top of link span 11, and the top of link span 11 is located in mounting hole 31 and tie bolt 3 and link span 11 are fixed by screw.
shown in each accompanying drawing, the top of wheel seat 12 is arranged with universal rotary table 2 regularly, namely lockout mechanism is located at for both being locked between universal rotary table 2 and underframe 101, thus the relative locking realized between link span 11 with wheel seat 12 and unblock, and then realize locking and the unblock of cardan wheel 1.Here, lockout mechanism comprises can be located at the locking piece 4 on underframe 101 by universal rotary table 2 relatively with moving, and this locking piece 4 has dead bolt 41, the outside perimembranous of universal rotary table 2 offers the locked groove 21 that can insert for dead bolt 41 correspondence, when dead bolt 41 inserts in locked groove 21, lockout mechanism locks; When dead bolt 41 spins off from locked groove 21, lockout mechanism unlocks.In the present embodiment, in the lockout mechanism of underframe 101 both sides, locking piece 4 is located at slidably on underframe 101 all in left-right direction and locks with universal rotary table 2 or unlock.Particularly, locking piece 4 also comprises sliding part 43, connects sliding part 43 and the connecting portion 42 of dead bolt 41, forms Z-shaped between sliding part 43, connecting portion 42 and dead bolt 41.Underframe 101 offers the chute 10a extended in left-right direction, the bottom of underframe 101 is also provided with the opening 10b be connected with chute 10a, sliding part 43 to be located at slidingly in chute 10a and connecting portion 42 through opening 10b, dead bolt 41 is positioned at the outside of underframe 101.
three-wheel vehicle 10 is also provided with the release mechanism for unlocking above-mentioned lockout mechanism, this release mechanism comprises to be located at for providing locking piece 4 along the elastic component 5 of its direction of slip elastic-restoring force, the unlocking operation part (not shown) be located on three-wheel vehicle 10, being connected to trailing cable (not shown) between unlocking operation part and locking piece 4 between locking piece 4 and underframe 101, and wherein elastic component 5 can adopt spring.Like this, when three-wheel vehicle 10 need drift about travel time, locking piece 4 away from universal rotary table 2, makes dead bolt 41 depart from locked groove 21 under the traction action of trailing cable, and lockout mechanism unlocks, thus makes cardan wheel 1 can universal rotational work; When three-wheel vehicle 10 needs straight-line travelling, operator operates unlocking operation part, trailing cable is discharged, like this under the resilient force of elastic component 5, locking piece 4 slides towards universal rotary table 2, make dead bolt 41 insert locked groove 21, lockout mechanism locks, thus makes the relative underframe of cardan wheel 1 101 fixing and can only linearly travel.Three-wheel vehicle 10 also comprises handlebar 102, unlocking operation part can be located on this handlebar 102, the trailing wheel 20 of both sides all carries out unlocking operation by this unlocking operation part, is not easy to use person like this and operates control at any time in the process of moving, thus immediately changes the motoring condition of three-wheel vehicle 10.
to sum up, child's tricycle of the present utility model, wherein wheel assembly 20 both can relatively underframe 101 universal rotational work and make three-wheel vehicle 10 drift about travel, also can relatively fix and make three-wheel vehicle 10 straight-line travelling by underframe 101, add the using function of this child's tricycle, too increase the interest that it uses simultaneously.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
